Some seethe as he strokes trophy (3,5)
I believe the answer is:
the ashes
'trophy' is the definition.
(cricket trophy)
'some seethe as he strokes' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'THE ASHES' is hidden within 'seethe as he strokes'.
(Other definitions for the ashes that I've seen before include "Trophy for winner of AngloAustralian cricket series" , "Cricketing trophy" , "Trophy awarded in England-Australia cricket, sounds grubby" , "trees" .)
